This is also known as Infrastructure-as-a-Service (IaaS).įile storage has been a popular storage technique for decades-it’s familiar to virtually every computer user, and it’s well-suited to storing and organizing transactional data or manageable structured data volumes that can be neatly stored in a database in a disk drive on a server. Moreover, you eliminate the expense of maintaining your own on-site hardware since this infrastructure is managed and maintained by the cloud service provider (CSP) in its data center. You simply pay a monthly subscription fee to store your file data in the cloud, and you can easily scale-up capacity and specify your data performance and protection criteria. These services allow multiple users to access and share the same file data located in off-site data centers (the cloud). To some extent, you can mitigate these scaling and performance issues with cloud-based file storage services. Scaling requires adding more hardware devices or continually replacing these with higher-capacity devices, both of which can get expensive. But, as the number of files grows, the file retrieval process can become cumbersome and time-consuming. Hierarchical file storage works well with easily organized amounts of structured data. To locate a file, all you or your computer system need is the path-from directory to subdirectory to folder to file. In file storage, data is stored in files, the files are organized in folders, and the folders are organized under a hierarchy of directories and subdirectories. File storage-also called file-level or file-based storage-is a hierarchical storage methodology used to organize and store data on a computer hard drive or on network-attached storage (NAS) device.
